Director Kenny, strong cast find the rituals in classic '70s play

When playwright Peter Shaffer's 'Equus' opened on Broadway 35 years ago, it wasn't easy to discern his purpose. Had he set out simply to craft a racketing good script with a philosophical undertow for audience members to puzzle over with their after-theater drinks? Or had he aimed higher? Today 'Equus' feels undated if not yet timeless. And it's as provocative as ever, especially in an energized New Edgecliff Theatre production.
